BALL-BEARING.

SPECIFICATION forming part of Letters Patent No. 634,898, dated October17, 1899. Application filed March l, 1899. Serial No. 707,305. (Nomodel.)

To all whom it may concern:

Be it known that I, GEORGE MILLEN, a citizen of the United States,residing at San Antonio, in the county of Bexar and State of Texas, have.invented a new and useful Ball- Bearing, of which the following is aspeciti cation.

The invention relates to improvements in ball-bearings.

rlhe object of the present invention is to improve the construction ofball-bearings for vehicle-wheels and to provide a simple andcomparatively inexpensive one adapted to reduce the friction to aminimum and capable of enabling the wear to be readily taken up when theballs become worn.

The invention consists in the construction and novel combination andarrangement of parts hereinafter fully described, illustrated in theaccompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure l is a longitudinal sectional view of aball-bearinghub constructed in accordance with this invention. Fig. 2 isa transverse sectional view on line 2 2 of Fig. 1. Fig. 3 is aperspective view of the spindle. Fig. 4 is a detail perspective view ofone of the adj ustableball-receiving collars. Fig. 5 is a similar viewof one of the caps or cups. Fig. 6 is a detail view of one of the enddisks or rings.

Like numerals of reference designate correspending parts in all theiigures of the drawings.

1 designates a metallic hub provided at its ends with inner andouterinterior recesses or chambers 3 and 3 and having a central hollowportion or chamber 4 separated from the end recesses or chambers 2 and 3byinterniediate solid portions 5 and 6, having central openings for thepassage of a spindle 8 of an axle, and these chambers 2 and 3 areadapted for the reception of the ball-bearings, which are arranged atthe inner and outer ends of the spindle.

As clearly illustrated in Fig. l of the accom panying drawings, eachball-bearing is constructed the same, with the exception that the innerbearing is slightly larger than the outer one. The spindle is providedwith inner and outer irregular portions 9 and 10, preferably formed byflattening the opposite sides of the spindle, as shown; but they maybeconstruct'- ed in any other suitable manner, and they re-l ceiveinnerand outer adjustable ball-support ing collars 11 and 12, conformingto the conigu ration of the irregular portions of the spinL dle, andthereby interlocked with the same. These ball-supporting collars areprovided with annular grooves or raceways for the reception of the innerand outer series of antifriction-balls 13 and 14, which are housedwithin inner and outer casings 15 and 16, each casing consisting of acap or cup 18 and a ring or disk 19, both provided with circularopenings to receive the spindle, and the ring or disk has an annularperipheral recess or rab- A bet 2O and is adapted to iit within the openend of the cap or cup of the casing. The balls bear against the interiorof the cap or cup, which gradually `tapers from its open end to providea gradually-decreasing interior diameter to take up the wear of theballs. The outer face of the casing is of the same diameter and isintended to be fastened Within the recess or chamber of the hub. Awasher 22 is shown interposed between the collar and the end of the capor cup; but a series of washers may be employed, if desired, and thesaid washer is adapted to be transferred to the opposite side of theball-supporting collar to shift the latter and move it into the @up orcap to take up the'wear of the balls. By this construction it will beclear that as soon as the antifriction-balls become worn the parts maybe readily arranged to take up the wear.

The circular o enines in the otherwise closed ends of the cylindricalcasings are designed to be about one-sixteenth of an inch greater indiameter than the diameter `of the spindle, so that should the ballsbecome Very much worn the spindle may iind its bearing in said openingsin the ends of the casings.

rlhe outer end of the spindle is threaded to receive an axle-nut, andthe easings 15 and 16 are provided with openings 23, adapted to form anentrance to the 'ball-races to permit the balls to be introduced thereinand also serving as oil-holes to enable the bearings to be lubricated.

The invention has the following advantages: The balLbearing, which issimple and comparatively inexpensive in construction, possesses strengthand durability and is ICO adapted to reduce friction to a minimum, andthe parts may be readily adjusted to shift the position of the balls andtake up the wear.

Changes in the form, proportion, size, and the minor details ofconstruction within the scope of the appended claims may be resorted toWithout departing from the spirit or sacrificing any of the advantagesof this invention.'

What is claimed isl. A device of' the class described comprising acasing with an interior bearing-Wall of regular taper and provided withclosed ends, a spindle passing through said ends, a bearing-collar onthe spindle adjustable with relation to said ends, and a device forspacing the collar from one end or the other of the casing.

2. A device of the class described comprising a casing, a spindle, and aball-supporting collar having a sliding and non-rotatable engagementwith the spindle and capable of adjustment longitudinally of the spindleto arrange the balls at different points in the casing, substantially asdescribed.

3. A device of the class described comprising a casing, a spindle havinga cross-sectionally irregular portion, au adjustable collar providedWith a ball-race and having an opening corresponding with the shape ofthe irregular portion of the spindle upon which said collar is adaptedto be slid in adjusting it, balls arranged Within the race, and a Washerinterposed between the collar and one end of thecasing and adapted to betransferred to the opposite side of the collar in adjusting the collarand position of the balls, substan tially as and for the purposedescribed.

-i. A device of the class described comprising a casing having atapering interior and designed to be mounted within a hub and secured tothe saine, a spindle having an irregular portion, a ball-supportingcollar mounted on the irregular portion of the spindle and capable ofadjstinentlongitudinally thereof, balls arranged within the groove ofthe collar, and means for adjusting the latter, substantially asdescribed.

5. A device of the class described comprising a hub provided at its endsWith recesses or chambers, casings mounted within the recesses orchambers of the hub and consisting of cups having removable rings ordisks, a spindle provided with inner and outer irregular portions, innerand outer ball-receiving collars mounted on the regular portions of thespindle, conforming to the coniiguration of the same and capable ofadjustment longitudinally ofthe spindle, balls interposed between thecollars and the casing, and Washers arranged on the spindle and adaptedto be transferred from one side of the collars to the other, to adjustthe balls, substantially as described.

In testimony that I claim the foregoing as my own I have hereto affixedmy signature in the presence of two witnesses.

GEORGE MILLEN.
